Are domed shower enclosures "out of style"?

When I moved to my current home almost 20 years ago I converted the 1st floor 1/2 bath/laundry to a full bath and installed a 36" domed shower enclosure. In all these years I have been very pleased with this enclosure--keeps heat & steam in, easy to clean, never leaks, no paint or tile needed, no cracked/peeling/mildewed ceiling paint. Well now I have a summer cottage and want to install the same thing there but nobody carries them anymore. Ultra-rare/special order. What happened to this great idea?
